The Sub-sewer is the sewer underneath the sewer. It is accessible via a giant toilet in the sewer; the El Chupanibre is flushed down it. Some claim that in the sub-sewers, there are a race of hideous sub-mutants. Most dismiss this as a sub-urban legend. In the comics it turns out that the sub-sewer is actually home to a utopian society of horrible people. Founded by enormous snobs trying to get away from other people the society today developed a form of speech based purely on biting sarcasm, meaning they always mean the opposite of everything they say.
